R devel - Mar 2009 - Follow-up on the wish for a visibility flag with tryEval ?

Dear list,

Did the wish for an official API for evaluating expressions while 
keeping an eye on the R_Visible flag (see:
https://stat.ethz.ch/pipermail/r-devel/2007-April/045258.html
) lead to something ?

I could not find a sign of it the current (R-2.8.1 and R-2.9-dev) R defines.


Thanks,


L.

You should read the NEWS file, where you'll find withVisible mentioned.
